Generative Engine Optimization (GEO): Get Cited in ChatGPT & Google AI

Right now, prospects in your city are asking ChatGPT, Google AI Overviews, and Perplexity for a recommendation. If your business is not appearing in those answers, you are invisible to a growing segment of high-intent buyers who never click a traditional search result. Generative Engine Optimization (GEO) — also referred to as Answer Engine Optimization (AEO), AI Search Ranking, and AI Visibility — is the discipline of building the structured data, entity authority, topical content, and citation signals that AI systems need to understand, trust, and recommend your business. Regardless of the term used, the goal is the same: ensure your business is cited when a potential customer asks an AI for a recommendation in your category. We build that foundation for local service businesses — and we measure success by whether AI systems actually cite you.

What Is GEO / AEO (Answer Engine Optimization)?

Generative Engine Optimization (GEO) — sometimes called Answer Engine Optimization (AEO), AI Search Ranking, or AI Visibility — is the practice of optimizing your online presence to appear in AI-generated search results. When someone asks ChatGPT for the best HVAC company in Vancouver, or Google AI Overviews surfaces a recommendation for a dentist, or Perplexity answers a question about personal injury lawyers — those answers are generated by AI systems that have learned to trust certain sources over others. GEO / AEO is the discipline of becoming one of those trusted sources. The terminology varies by platform and practitioner: Google tends to use "AI Overviews optimization," SEO professionals often say "GEO" (Generative Engine Optimization), while others use "AEO" (Answer Engine Optimization), "AI Search Ranking," or simply "AI Visibility." At CastleCS, we use GEO as our primary term — but our program is designed to improve your visibility across all AI search surfaces, regardless of what they are called.

How GEO Works

AI search systems generate recommendations based on several signals:

Entity authority: how well-defined and consistently described your business is across the web
Structured data: Schema.org markup that tells AI systems what your business does and where
Citation signals: mentions and links from authoritative sources in your industry
Topical authority: the depth and quality of content covering your core services and service area
Review signals: the volume, recency, and sentiment of your Google and third-party reviews

GEO vs. Traditional SEO: What Is Different

Traditional SEO optimizes for ranking in the blue-link results on Google. GEO optimizes for being cited in AI-generated answers. The two disciplines overlap significantly — strong traditional SEO is a prerequisite for GEO — but GEO requires additional work: structured data implementation, entity disambiguation, citation building, and content designed to be quoted by AI systems rather than just ranked by them.

What We Build for Your GEO Program

Schema.org structured data implementation across all key pages

Monitoring and reporting: tracking your citation frequency in ChatGPT, Perplexity, and Google AI Overviews

Frequently Asked Questions

How do you measure GEO results?

We measure GEO results by tracking your citation frequency in AI search systems. This includes manual and automated testing of relevant queries in ChatGPT, Google AI Overviews, and Perplexity, tracking how often your business is mentioned or recommended in response to relevant queries in your service area.

How long does GEO take to show results?

GEO programs typically show meaningful results within 3 to 6 months. The timeline depends on your starting position, the competitiveness of your market, and the scope of the program. Businesses with strong existing SEO foundations typically see faster results.

Is GEO the same as SEO?

GEO and SEO overlap significantly but are not the same. Traditional SEO optimizes for ranking in Google blue-link results. GEO optimizes for being cited in AI-generated answers. Strong traditional SEO is a prerequisite for GEO, but GEO requires additional work: structured data, entity authority building, and content designed to be quoted by AI systems.

Which AI search systems do you optimize for?

We optimize for the major AI search systems: Google AI Overviews (formerly Search Generative Experience), ChatGPT, Perplexity, and Microsoft Copilot. We also monitor emerging AI search systems as they gain market share.

Do I need GEO if I already have good traditional SEO?

Yes. Traditional SEO and GEO are complementary but distinct. A business can rank well in traditional Google search but be invisible in AI-generated answers — and vice versa. As AI search becomes a larger share of how people find local businesses, GEO is becoming as important as traditional SEO.

Can GEO help my business appear in voice search results?

Yes. Voice search results from Google Assistant, Siri, and Alexa are increasingly powered by AI systems that use the same signals as AI search. A strong GEO program improves your visibility across all AI-powered discovery channels, including voice search.

Google Review

“They helped us show up in AI-generated legal recommendations — something I didn't even know was possible. When someone asks an AI assistant for a family lawyer in Vancouver, we come up now. That's new territory and CastleCS got us there.”
